A »To diagnose electrical faults, set your multimeter to the correct function: voltage (V) for checking power, resistance (Ω) for continuity, and current (A) for flow. For voltage, connect probes across the circuit; for resistance, ensure no power is flowing and connect probes across the component; for current, connect in series with the circuit. Always start with the highest range setting for safety!

A »To diagnose electrical faults, set a multimeter to the correct function: DC voltage (V) to measure voltage, ohms (Ω) to measure resistance, and amps (A) to measure current. Connect leads accordingly and take readings. Compare results to specifications to identify faults. Ensure the circuit is off when measuring resistance.
